Problem summary

• ****************************************************************
  * USERS AFFECTED: All CICS users.                              *
  ****************************************************************
  * PROBLEM DESCRIPTION: Simultaneous LINKs to Liberty results   *
  *                      in DFHSJ1006 timeouts.                  *
  ****************************************************************
  When two LINKs to Liberty occur simultaneously the second LINK
  will fail and a DFHSJ1006 timeout will occur with message:
  DFHSJ1006 E date time applid userid An attempt to attach to
  JVMSERVER server_name has failed because the Liberty link
  request has timed out.
  
  In a busy system, DFHSJ1006 timeouts may not be observed,
  but instead intermittent slow response times from LINKs to
  Liberty programs that aren't picked up until a subsequent LINK
  is issued.
  

Problem conclusion

• CICS has been fixed so that simultaneous LINKs to Liberty do not
  interfere with each other.
  

Temporary fix
